Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

Use these fittings for low-pressure applications in noncorrosive environments.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

For excellent strength in extreme-pressure applications, choose these heavy duty Class 1500 flanges.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Use these heavy duty forged flanges for high-pressure applications.

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Class 125 fittings, they are built for use in low-pressure applications.

Extreme pressures are no problem for these heavy-duty brass fittings.

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Also known as Silbraze fittings.

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Class 150 flanges. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Class 150 flanges.

Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket to create an access point within a line.

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Also known as dry disconnects and double shut-off couplings, these have a shut-off valve in the plug and socket for minimal fluid loss when disconnecting the hose line.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Attach these fittings to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Couplings consist of a plug and a socket that connect more quickly than threaded garden hose couplings. To connect, insert the plug into the socket and press the levers down.

These caps are the fastest way to close off or access your water line. They have a bracket that snaps into any type of 2 1/2 size female fire hose threads. Tap on one of the pin lugs to remove quickly in an emergency.

Tighten these threaded fittings with your hands for a secure connection in testing, flushing, venting, and plugging applications—no tools, tape, or sealant required.

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering.

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window.
